Sentinel-2 L2A true color, read at 20 m. One pixel is 0.04 ha. A strip narrower than about 40 m can hold skiable snow and show nothing. By mid-September, north-facing cirques sit in shadow at the late-morning overpass, so one zero isn't proof of anything.
How we got to this status
The Sep 24 pass was cloudy over the site (100%), so a cloudy pass counts as no look, not as zero. This uses the Sep 22 pass.
Sep 22 pass fully covers the site and is clear over it.
No snow pixels in the window (under 3 px counts as zero).
Not flagged as possible new snow.
A second clear zero in a row (after Sep 12), so it reads Gone.
A ground report from Sep 22 is less than 10 days old, so it's shown first until Oct 2.

Small but skiable. Photos pending.
The satellite reads 0 px here, so this report is what's shown on the site until Oct 2. The strip is likely narrower than the ~40 m the satellite can see.

Enough snow to ski on Sep 18. Not visible as a lasting patch at 20 m; likely new snow from the Sep 17 storm or a strip < 20 m wide.
